PUSH-SWITCH.

Specification of Letters IE atent.

Application filed June 16, 1916. $eria1No. 104,112.

To all whom it may concern:

Be it known that I, J OHANN G. PETERSON, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Push- Switches, of which the following is a specification.

This invention relates to push-switches. There are certain kinds of this type of switch which comprise a receptacle, a metallic bracket within the receptacle supporting certain of theoperative parts and a metallic cross bar, bridge or plate which extends across the open side of the receptacle and is attached thereto in some convenient way, this cross bar generally providing a means for mounting the switch. One of the primary purposes of the invention is to provide means of an effective nature by which this cross bar can be insulated from the bracket and preferably at the same time supported between its ends by the-insulating means of whatever character the same may be.

In the drawings accompanying and forming part of the present specification I have shown in detail one convenient form of embodiment of the invention which I will set forth fully in the following description. I do not, however, restrict myself to this particular disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings:

Figure 1 is a top plan view of a switch involving the invention.

Fig. 2 is a similar view with the cross bar and insulating lining removed.

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1, looking in the direction of the arrows.

Fig. 4c is a transverse section on the line 4L4 of Fig. 3, looking in the direction of the arrow.

Like characters refer to like parts throughout the several views.

The switch represented comprises in its make-up a receptacle or box as 2 generally made of insulating material, porcelain or some convenient composition answering satisfactorily in this connection. Across the open side of the receptacle or box the plate, bridge or cross bar 3 extends, this cross bar or plate being fastened to the body or receptacle 2 in any suitable manner as by screws in the ordinary way. The cross bar between its ends is perforated to receive the buttons 4: at the upper ends of the levers 5, the cross bar obviously presenting a guide for the buttons and levers. In the chamber of the receptacle or body 2 is a metallic bracket 2"fastened to the bottom thereof by screws or otherwise as familiar. Associated with the levers is the switching member 6 supported by the spindle 7 the terminals or end contacts of the switching member being cooperative with contacts as 8 fastened by screws or otherwise to the body or receptacle 2, the levers 5 acting upon the switching member 6 through snap means as well understood in the art. As a matter of fact the foregoing is a brief description of a familiar type of switch in which my invention can be advantageously incorporated, although as will be inferred I do not restrict myself to the use of the invention in conjunction with this particular form of switch. The top of the body 2 is internally rabbeted to receive the insulating lining 9 across which the metallic bar or plate 3 extends. Said lining has perforations registering with those in the cross bar or plate 3, for the reception and movement of the buttons 4. 1

From the body of the bracket or frame 2 the parallel arms 10 extend, these arms jointly presenting a fork and constituting a convenient carrier for the insulating element 11 preferably but not necessarilycmade in one piece. This insulating element or block 11 is slotted near its ends as at 12 to snugly receive the prongs or projections 13 at the free or outer ends of the arms I0.

All

The insulating block 11 fits flatwise against lates the two parts. The block serves a further function in that it presents an advantageous support for the cross bar 3 between the ends of the latter.

As shown said cross bar has between its ends the boss or protuberance 14 of two diameters, the portion of largediameter fitting theperforation or hole15 in the lining 9, while the portion of less diameter fits body, a cross bar extending across the open side of the body, and an insulatin block connected with the frame for insulatlng the frame from the cross bar and for also supporting the cross bar between the ends thereof.

2. A switch comprising a chambered body open on one side, a metallic frame in the body, a cross bar extending across the open side of the body, and an insulating block connected with the frame for insulating the frame from the cross bar, the cross bar-hav- 'support the cross bar an In additiom ing a projection and the block having an opening to receive the rojection to thus 5 prevent the same from moving laterally.

3. A switch comprising a chambered body open on one side, a metallic frame in the body, a cross bar extending across the open side of the body, the frame being provided with means to support the cross bar between the ends thereof and for also insulating the cross bar and the frame from each other.

4. A switch comprising a chambered body open on one side, a metallic frame in the body, a cross bar extendin across the open side of the body, an insu ating block, the

frame having side arms provided with projections and the block having slots to receive said projections, the block being sustained by the arms and supporting the cross bar between the ends thereof.

5. A switch comprising a chambered body, a metallic frame in the body, a cross bar extending across the open side of the body, and an insulating block supported by the frame for insulating the frame from the cross bar, the block supportin the cross bar and the two being interlocke In testimony whereof I aflix my signature in the presence of two witnesses.
